Abstract：
BACKGROUND: Speech-language pathologists/Otolaryngologists recognize high prevalence of speech and language disorder among children. The aim of the study is to find out the epidemiological profile of speech and language disorder in north central Nigeria.
METHODS: A five year retrospective review of all referral to speech and language therapy unit ENT Department between January 2005 and December 2009. Information retrieved and analysed included bio-data, clinical presentation and diagnosis of the patients. Descriptive analysis of these data were done.
RESULTS: A total of 146 patients were seen out of which 89 (61%) were under five, 32 (21.9%) were between 5-10 years, 20 (13.7%) in the range of 11-20 yrs and 2 (1.4%) were between 21-34 yrs. None was observed in the elderly. Male preponderance was noted with male to female ratio of 1.9:1.0. The commonest diagnosis was deaf-mutism in 84 (57.5%) followed by delayed speech development in 31(21.2%) patients. The least diagnosis was aphasia in 2 (1.4%) patients.
CONCLUSIONS: Speech and language disorder was commonest among the under five\'s with non in the elderly, There was a higher prevalence amongst males and deaf-mutism was the commonest observed.

摘要：
背景：言语语言病理学家/耳鼻喉科医师认识到儿童中言语和语言障碍的患病率很高。该研究的目的是找出尼日利亚中北部言语和语言障碍的流行病学特征。
方法：对2005年1月至2009年12月耳鼻喉科语音和语言治疗部门的所有转诊进行了为期五年的回顾性回顾。检索和分析的信息包括生物数据，患者的临床表现和诊断。对这些数据进行描述性分析。
结果：共146例患者，其中89例（61%）为5岁以下，32人(21.9%)在5-10年之间，在11-20年范围内的20例（13.7%）和21-34年之间的2例（1.4%）。在老年人中没有观察到。男性占优势，男女比例为1.9：1.0。最常见的诊断是84例（57.5％）的聋哑症，然后是31例（21.2％）的言语发育延迟。诊断最少的是失语症2例（1.4％）。
结论：言语和语言障碍在5岁以下老年人与非老年人中最为常见，男性患病率较高，聋哑症是最常见的。
